Liquid ethanol flows over a water soaked pad at a low Reynolds number in an indu

Question

Liquid ethanol flows over a water soaked pad at a low Reynolds number in an industrial process. If the Schmidt for the ethanol is 1200, the concentration boundary layer grows faster than the momentum boundary layer. This statement is:

Liquid ethanol flows over a water soaked pad at a low Reynolds number in an industrial process. If the Schmidt for the ethanol is 1200, the concentration boundary layer grows faster than the momentum boundary layer. This statement is: 2) A) True B) False C) False only if the water is hotter than the ethanol D) Annoying to all people

Explanation / Answer

schmidt number is defined as the ratio of momentum diffusivity (kinematic viscosity) to mass diffusivity.  

it means the concentration diffusion (denominator) is very less which shows that the concentration boundary layer grows at a very slow rate than the momentum boundary layer.

Hence the statement is FALSE
